PrepHarbor helps your family prepare for emergencies, power and water outages, loss of heating or mobile service, and evacuation. Estimate supplies, review your emergency kit and save an action plan. Core preparedness tools and survival guides work offline after installation.
Water and food supplies:
Calculate drinking water and food reserves using your own circumstances. Use the calorie calculator to estimate calories, protein, fat and carbohydrates. Search the food database and adjust quantities to plan your supplies and daily meals.
Emergency kits and planning:
Review your go-bag, household self-sufficiency, shelter conditions and walking route. Assess cold-related risk factors. Build a schedule of short phone or radio communication sessions based on device battery levels and family size.
Emergency action plans:
Prepare for evacuation within an hour, an extended blackout, a water outage or a home that becomes too cold. Explore what to do during an air raid alert, loss of mobile service, separation from family members, getting lost in a forest or a vehicle breakdown far from a settlement.
Offline survival and safety reference:
Read practical guides on safe water, first aid, sanitation without water and navigation without connectivity. Learn about fire safety, carbon monoxide poisoning, emergency utility shutdown and a vehicle emergency kit. Consult the radio frequency reference and open large cards showing light, sound and visual distress signals.
Keep your plans on your device:
Save calculations and drafts, discuss preparedness with your family and update your plans when supplies or circumstances change. The interface and food names are available in 10 languages. External links may require internet access. The app does not contact rescuers or transmit an SOS.
Calculations are estimates and do not guarantee safety. PrepHarbor is not a medical device and does not diagnose, treat, cure or prevent any medical condition. Consult a qualified healthcare professional for medical advice, diagnosis or treatment. In immediate danger, contact local emergency services and follow official instructions.
